Abstract
Finding markers to detect and identify compounds and components related to an explosive is an important task that could reduce threats of unlawful uses of explosives. The capability of Raman spectroscopy to characterize chemical composition of explosive compounds and the analysis of stable isotope ratios could be useful to identify specific markers to identify the origin of the material used. Using Raman spectrometer directly on-site after the accident scene could be a useful tool for an immediate characterization of the components. In addition, carbon and nitrogen analysis on some fragments collected on the accident scene will then confirm the characterization of the components. The proposed configuration of double technique, coupled with a digital database and algorithms, could be useful to run analysis, with fast response time, in work environment related to emergency situations.

The peaks are well-distinct even in the case of a mixture. Their relative intensity depends on their initial ratio, but not the absolute position in terms of Raman shift. This means that the Raman spectroscopy technique has the potential to recognize the presence of explosive substances, even when they are mixed with others
Summary
Explosives have a huge number of useful civil applications, but there are numerous malicious usages connected to the growing threat of terrorism activities. The seat of the blast, will contain explosive residues or bits of the device, which could reveal the original content of the chemical explosive [30, 31]
